Small testcase:
template <class a> class __attribute__ ((visibility ("default"))) vector {
public:
  vector(){t=2;};
  void push_back(a){t++;};
  int t;
};

class __attribute__ ((visibility ("hidden"))) Foo {
 public:
 int m() {
   return 0;
 }
};


int main(void) {
 vector<Foo> v;
 v.push_back(Foo());
 return 0;
}

Everything should be hidden except for main().
